Assessment Rubric Overview: "Message Delivery System"

In this assessment, candidates are tasked with implementing a message delivery service that incorporates a rate-limiting algorithm to prevent the delivery of duplicate messages within a specified time frame. This problem evaluates a candidate's proficiency in data structures, algorithm design, and system optimization, aligning with Canva's emphasis on practical problem-solving and technical excellence.

Core Competencies and Skills Evaluated:

• Data Structures and Algorithms: Candidates should demonstrate a solid understanding of data structures such as hash sets or queues to efficiently track message timestamps and manage delivery statuses. Proficiency in algorithm design, particularly in implementing rate-limiting mechanisms, is essential.

• System Design and Optimization: The ability to design scalable and efficient systems is crucial. Candidates should consider time and space complexity, ensuring that the solution can handle high volumes of messages without degradation in performance.

• Coding Proficiency: Clean, readable, and well-documented code is expected. Candidates should adhere to best practices in coding standards and demonstrate attention to detail in their implementation.

Behavioral Traits and Problem-Solving Approaches Assessed:

• Analytical Thinking: The ability to break down complex problems into manageable components and devise effective solutions is key. Candidates should showcase logical reasoning and structured problem-solving approaches.

• Attention to Detail: Ensuring that edge cases are handled appropriately and that the solution is robust against various input scenarios reflects a candidate's thoroughness and precision.

• Adaptability and Learning: Given Canva's dynamic environment, candidates should exhibit a growth mindset, demonstrating the ability to learn new concepts and adapt to evolving requirements.

Assessment Process Expectations:

Canva's interview process is designed to be a two-way conversation, allowing candidates to showcase their skills and learn about the company. The process typically includes:

1. Initial Screening: A conversation with the Talent Acquisition team to discuss the candidate's background and the role.

2. Technical Interviews: These may involve live coding sessions, system design discussions, and problem-solving challenges. For engineering roles, a peer-to-peer technical interview is conducted, including a problem-solving challenge. (glassdoor.com)

3. Take-Home Challenge: Candidates are given a brief to complete in their own time, allowing them to showcase their thinking and work style. This step is designed to see the candidate's personality and authentic self shine. (glassdoor.com)

4. Final Interview: A comprehensive interview combining technical problem-solving with behavioral questions, providing an opportunity to discuss previous experiences and how they align with Canva's values. (glassdoor.com)
